On the connectivity of Milnor fiber for mixed functions

In this note, we prove the connectivity of the Milnor fiber for a mixed polynomial $f(\mathbf{z},\bar{\mathbf{z}})$, assuming the existence of a sequence of smooth points of $f^{-1}(0)$ converging to the origin. This result gives also a another proof for the connectivity of the Milnor fiber of a non-reduced complex analytic function which is proved by A. Dimca
